Yesterday it was announced that GNOME 3.0 is delayed till next year. The extra time has given the Shell Developers some more time to play around with new concepts and they have come up a new mockup. Here are the new mockups.

But scaled up to be used on the desktop. I don't think this interface will scale well, but I hope so. I am currently prototyping those mockup using the Awesome Desktop Shell prototyping framework (AwesomeWM). I will see how it work, I may use those concepts if it work well. After all, I have never been a great fan of the current standardized desktop UI.
